In this paper, we present a meta-heuristic algorithm for the well-known resource-constrained project scheduling problem with discounted cash flows. This optimization procedure maximizes the net present value of project subject to the precedence and renewable resource constraints. The problem is...

In this paper, we present a new genetic algorithm for the resource-constrained project scheduling problem with discounted cash flows and investigate the trade-off between a project’s net present value and its corresponding lead time. We consider a problem formulation where the pre-specified...

In this paper, we tackle the problem of scheduling multisite and multimode activities in order to minimise the project duration that meets the constraints imposed by limited resources. The industrial system is composed of many production sites, and each site has its own resources called local...

The Net Present Value maximizing model shows fallacies and inconsistencies that may be easily unmasked by performing a cognitive analysis of the decision-making process implied by the maximization problem. The model may be conveniently rescued if the maximizing version of the criterion is shunt...

We consider a capital budgeting problem in which each potential project requires the performance of a known set of activities. In general, these sets of activities are not mutually exclusive. However, when a particular activity is common to the requirements of multiple projects, a single...

The production-distribution system design is an integral part of the general supply chain design. This paper proposes a novel solution methodology for this problem that is based on Lagrangean relaxation, interior-point methods, and branch and bound. Unlike classical approaches, Lagrangean...

This paper investigates the solution of the linear programming (LP) relaxation of the multi-commodity flow formulation of the multiple-depot vehicle scheduling problems arising in public mass transit. We develop a column generation technique that makes it possible to solve the huge linear...
